Color Manager is a program for recoloring and manipulating existing icon packs, themes and wallpapers. The program is designed for NovaOS (or any Linux distribution), but is expected to work on anything that runs python. If you publish anything that was generated using this program, make sure to credit the original creator and this repository.
Below are examples of what can be done using this library. Using it in a simple python script, you can define a pipeline to automatically customize assets exactly as you see fit.
Now also supports pngs and jpegs!
Add customizable backdrops to all your icons.
Examples | rounding=0.0 |
rounding=0.5 |
rounding=1.0 |
---|---|---|---|
padding=0 color="#000000"
|
|||
padding=2 color="#112288"
|
|||
padding=4 color="#551144"
|
In these examples, my own theme and icon-pack have been recolored for inspiration. These are available for download under releases.
Nord | Woodland | Beach |
These are simple monochromatic recolors of my own theme and the papirus icon pack. Multichromatic recoloring based on a palette or mapping also works. Recoloring works on any svg/css/png/jpg/xml-based theme, which include GTK-, Cinnamon-, Gnome-shell- and metacity-themes.

The program is also available with a graphical frontend. Features for this may lack slightly behind.
Either import utils
into your own script and call its functions, e.g.:
from color_manager import utils
Recoloring collections:
src = "test/graphics" # Also try "test/theme"
name = "my_pack"
dest = "~/Downloads"
color = (0.5, 0.5, 0.5) # = rc.norm_hsl(180, 50, 50)
palette = "palettes/nord.json"
mapping = "mappings/renord.json"
utils.recolor(src, dest, name, color) # Either color, palette, or mapping.
Extracting color palette:
image = "test/graphics/imgs/lake_cabin.png" # Also try an svg.
num_colors = 10 # May be any number.
output = "resources/palette.png" # Optional - saves colors as image.
utils.extract_colors(image, num_colors, output)
Adding backdrops to svg icons:
src = "test/graphics"
name = "my_pack"
dest = "~/Downloads"
color = "#000000" # Optional - Defaults to black.
padding = 0 # Optional - Between backdrop and edge.
rounding = 0.5 # Optional - Between 0 and 1, i.e. rectangle and ellipse.
utils.add_backdrop(src, dest, name, color, padding, rounding)
Or launch the GUI by running python3 color_manager/gui.py
in a terminal from the project's root directory. The GUI will adopt your active theme. Dependencies: basic_colormath
, tqdm
and pillow
. For the GUI, pygobject
(GTK bindings) must also be installed.
Defining a palette or mapping is either done as a dict-object or as an external json-file, e.g.:
my_palette = {
"type": "palette",
"name": "...",
"desc": "...",
"smooth": True,
"colors": [
"#ffffff",
"#000000",
...
]
}
my_mapping = {
"type": "mapping",
"name": "...",
"desc": "...",
"smooth": True,
"map": {
"#ffffff": "#000000",
"#f0f0f0": "#0f0f0f",
...
}
}
Examples of both as json-files are available in this repository.
Currently, three operations are supported:
Type | Result | Speed | Support |
---|---|---|---|
Monochromerecoloring | A monochromatic variant, colored by appropriate shades of the provided base color. | ~5000svg/s ~500png/s | svg, xml, css, png, jpg |
Paletterecoloring | A multichromatic variant, where all colors are replaced by their nearest perceived equivalent that adheres to the provided color palette. | ~100svg/s ~3png/s | svg, xml, css, png, jpg |
Colorremapping | A multichromatic variant, where all colors that are specified in a given map will be replaced as dictated by said map. | ~1000svg/s ~10png/s | svg, xml, css, png, jpg |
Extractcolors | Returns and optionally saves the color palette of an image, in specified detail. | ~10colors/s | svg, xml, css, png, jpg |
Addbackdrop | Add a rectangular or elliptical background (and anything in between) to all svg icons. | ~5000svg/s | svg |
Speeds were recorded with an Intel i7-4770K CPU and is strongly dependent on file sizes. Any asset can serve as the base for any color palette or base color. Svg/css recolorings will always be perfect, but png/jpgs may require experimentation.
Tip: To increase the quality, i.e. decrease the perceived noise of multichromatic recolorings of pngs/jpgs, either...
Image.quantize()
from pillow
.smooth
to true
/false
in the palette json file.If you are experienced with packaging projects such as this for easy distribution, i.e. as deb, appimage or flatpaks, any contributions of your will be most welcome.
